SIPHON WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 399,184, dated March 5, 1889.

Application filed October 26, 1888 Serial NO. 289,173 (N0 model.)

To all whom it may oil/Leora:

Be it known that l, llLcH ll. CRAlGlE, of Stamford, l airlield county, Connecticut,have invented an Improved Siphon \ater-(loseh of which the following is a specification.

The object of my invention is to provide a water-closet in which a thorough and clientive evacuation of its contents will take place when water is admitted to the closet, which j with a service-pipe, E, that extends from an closet shall be simple in construction and not liable to leakage or to permit the escape of gases.

The invention consists in the details of llll provement, and the combinations of parts that will be more fully hereinafter set forth. 1 Reference is to be had to the accompanying drawings, fori'ning part of this specification, in which Figure l is a side elevation ol a water-closet containing my improvements. Fig. 2 is a plan view thereof. Fig. 3 is a vertical longitudinal section on the line a c, Fig. 2. Fig. 4c is a detail horizontal section on the line 7r; 7:, Fig. 3. Fig. 5 is a similar View on the line 7r. 1:, Fig. 3; and Fig. 6 is a vertical cross-section on the line c c, Fig. 1.

In the accompanying drawings, the letter A represents the bowl of a water-closet, which may be of suitable shape. In the lower part. of the bowl A is an opening, (I, that communicates with a siphon, B. The siphon B consists of two parallel tubes, 1) d, that are connected at their upper ends, as shown in Fig. 3. Thelower end of the tube 1) communicates with the opening a in the bowl A, and is what I term the short leg of the siphon. The lower end of the tube (Z may be connected in any suitable manner with the soil-pipe 6. (See Fig. 3.)

I prefer to form the bowlA and the siphon B in one piece of earthenware, so that there will be no joints to permit leakage.

Atthe bottom of the water-closet bowl A is a jet-opening,f, that is in line with the short leg I; of the siphon B, and that communicates with the lower part of the bowl A. This jetopening f is in communication with a pipe, D, that extends upwardly along the side of the bowl A, and terminates near the upper edge of said bowl. I prefer to make the pipe D, jet-opening f, and bowl A in one integral I piece of earthenware or other suitable material, so that there will be no danger of parts becoming loosened below the level of the water in the bowl, thereby preventing leakage.

The pipe D, I prefer to make considerably larger than the jet-opening f, so that water pas. ng through the pipe I) will. issue from the jet-opei'ling f with considerable force.

The upper end of the pipe D is connected m*erhead tank or from other suitable water- I supply. The pipes D and E may be connected together by a eoupliu g, g that inn-3 be of any ordinary or suitable construction. The water from the tank or other source of supply passes from the service-pipe 1*. to the pipe D, and thence issues from the jet-opening f with great force up into the short leg b of the siphon lithereby causing the water contained in the siphon to pass from the leg Z) into the leg (Z of the siphon, thereby starting the siphoning of the water from the bowl and cansin g a complete evacuation thereof.

From the pipe D, pre'l'erably near its upper end, atube, 71., extends upwardly, as clearly shown in 'Fig. (i, which tube opens into the bowl A, near its upper edge, as at "i, directly in line witha shield, j, that is carried on the inner side of the bowl A; but, if preferred, the tube 71 could communicate with a perforated flushing-riin that extends around the upper edge of the bowl, as in ordinary waterelosets. The water issuing from the tube h is the flushing-water for the bowl and passes along the inner side of the bowl to clean the same. I preterto connect the tube 72 with the pipe D, slightly below the coupling g on the same, as will be seen by dotted line in Fig. 1.

The water acts in my improved water-closet to evacuate and fill the same, as follows: Suppose the bowl A to be supplied with water extending up in theleg b of the siphon about as shown in Fig. 3. Voter is now admitted to the bowl to evacuate the same, which water passes from the service-pipe E through the coupling g into the pipe D, down through the same, and issues with great force from the j etopcningf, beingdirected from said opening up into the short leg I) of the siphon. As the water thus passes up into the siphon, it forces the water eontained in the siphon up over the sealing-poin t,

Lil

thereby starting the siphoning. This siphoning draws all the water and other matter from the bowl up through the short leg I) and discharges it into the downwardly-extending leg (I, from whence it passes to the soil-pipe. \Vhile the siphoning is taking place water is still issuing from the jet-opening f and passing up the short leg I) of the siphon, which assists in the evacuation of? the water-closet, causing any solid matter that may be contained therein to quickly flow out. \Vhcn the water is admitted to the pipe D, it seeks an outlet through the jet-opening f, but as said opening is much smaller than the pipe D the excess of water will back up in the pipe D until it reaches the opening of the tube 72, when it will pass up through said tube and act to flush the bowl by issuing from the opening i and from behind the shield j, orby passin g from the ordinary perforated flushing-rim, as before described. From thisit will be seen that the flushing-waiter for the bowl does not enter the same by a direct downward flow of water from the tank or other water-supply; but that after the water has begun to issue from the jet-opening f to evacuate the bowl the excess of water contained in the pipe D passes upwardly from said pipe to the upper edge of the bowl A.

As will be seen from the drawings, I connect the service-pipe with the jet-supply pipe D above the normal level of the water in the bowl. By this means if the coupling-conned tions between the pipes 'D and E should become loosened from any causethewaterfrom the bowl A cannot flow out or leak from this eoupling-conneetion. \Vhere the connection has been made below the water-level in the bowl, as in the water-closets heretofore constructed,if any leak occurred at the coupling the water from the bowl would leak out and do much damage in the building. By arranging the tube 72v so that the water will begin to flush the bowl after the water from the jetopening f has started the siphon and the evacuation of the water-closet the flushing-water will not begin to fill the bowl while the bowl is being evacuated. By this means I effect a complete and thorough evacuation of the bowl. The water will continue to flow from the jetopening f and up the shortleg l) of the siphon after all the water has passed from the bowl and until the at'terflow takes place for replenishing the bowl with water. This afterflow begins as soon as the stream. from the pipe D is divided, part escaping through flushing-opening z' and the remainder through jetopening f; but the latter part of the divided stream will not be strong enough to ascend the siphon, and will therefore help fill the bowl.

Having n ow described my invention what I claim isl. The bowl A, having flushing-aperture 2' and water-supply pipes D 71 the pipe It being wholly above the normal level of the Water in the bowl andleadin g upward to said aperture '1", and the pipe D extending higher than its connection with the pipe 71, substantially as described. i

2. The bowl A, having flushing-aperture 'i and water-supp] y pipes D 72., the pipe hbeing wholly above the normal levelof the waterin the bowl and leading upward to said aperture i, and the pipe D extending higher than its connection with the pipe 71, in combination with the lower jet-nozzle, f, and siphon B, substantially as described IIU HI II.
